OBJECTIVE To test the hypothesis that high circulating concentrations of maternal anti-angiogenic factors are associated with increased risk of respiratory distress syndrome (RDS). STUDY DESIGN This is a nested case-control study of nulliparous women who delivered less than 37 weeks of gestation within the Calcium for Preeclampsia Prevention (CPEP) trial. The study included 116 women with pre...

Risk factors for the development of respiratory distress syndrome and transient tachypnoea in newborn infants. C. Dani, M.F. Reali, G. Bertini, L. Wiechmann, A. Spagnolo, M. Tangucci, F.F. Rubaltelli, and the Italian Group of Neonatal Pneumology. #ERS Journals Ltd 1999. ABSTRACT: Respiratory distress syndrome (RDS) and transient tachypnoea (TT) are the most frequent acute respiratory diseases i...

Respondent-driven sampling (RDS) is a network-based form of chain-referral sampling used to estimate attributes of populations that are difficult to access using standard survey tools. Although it has grown quickly in popularity since its introduction, the statistical properties of RDS estimates remain elusive. In particular, the sampling variability of these estimates has been shown to be much...

Vertebrate vision requires photon absorption by photoreceptor outer segments (OSs), structurally elaborate membranous organelles derived from non-motile sensory cilia. The structure and function of OSs depends on a precise stacking of hundreds of membranous disks. Each disk is fully (as in rods) or partially (as in cones) bounded by a rim, at which the membrane is distorted into an energeticall...

BACKGROUND This article examines the ethical implications of using respondent-driven sampling (RDS) to conduct HIV behaviour surveillance among injection drug users (IDUs) in Chicago. Ethnographic inquiry illustrates how the design and implementation of RDS invites if not promotes manifold violations of federal guidelines governing human research subject protections. METHODS Post hoc structur...

The outer segments of vertebrate rod photoreceptor cells consist of an ordered stack of membrane disks, which, except for a few nascent disks at the base of the outer segment, is surrounded by a separate plasma membrane. Previous studies indicate that the protein, peripherin or peripherin/rds, is localized along the rim of mature disks of rod outer segments. A mutation in the gene for this prot...

OBJECTIVE To determine whether the SP-B deficiency and gene mutations in exon 4 is associated with neonatal RDS in China Han ethnic population. METHODS The study population consisted of 40 neonates with RDS and 40 neonates with other diseases as control in China Han ethnic population. We Compared SP-B expression in lung tissue and bronchoalveolar lavage fluid with immunoblotting, and analyzed...

Peripherin/rds is an integral membrane protein required for the elaboration of rod and cone photoreceptor outer segments in the vertebrate retina; it causes a surprising variety of progressive retinal degenerations in humans and dysmorphic photoreceptors in murine models if defective or absent. (Peripherin/rds is also known as photoreceptor peripherin, peripherin/rds, rds/peripherin, rds, and p...

The in-plane optical anisotropy (IPOA) in InAs/GaSb superlattices has been studied by reflectance difference spectroscopy (RDS) at different temperatures ranging from 80 to 300 K. We introduce alternate GaAs- and InSb-like interfaces (IFs), which cause the symmetry reduced from D 2d to C 2v . IPOA has been observed in the (001) plane along [110] and [1[Formula: see text]0] axes. RDS measurement...
